Abstract
A lens antenna array system is provided that includes a plurality of communication links. The lens antenna array system uses beam index modulation to select an active subset of communication links from the plurality of communication links. The selection of the active subset of the communication links constitutes the transmission of a digital word.
Claims30
A method of wireless communication for a lens antenna array system, comprising:
- selecting a first subset of transmit antennas from an array of transmit antennas arranged in a focal region of a first lens;
- transmitting from each transmit antenna in the first subset of transmit antennas to form a plurality of first RF signals that are directed through the first lens toward a second lens for a first symbol interval;
- selecting a second subset of transmit antennas from the array of transmit antennas;
- and
- transmitting from each transmit antenna in the second subset of transmit antennas to form a plurality of second RF signals that are directed through the first lens towards the second lens for a second symbol interval.

A method of wireless communication comprising:
- transmitting a first plurality of RF signals over a first symbol interval from a first subset of transmit antennas in an array of transmit antennas arranged in a focal region of a first lens in a lens antenna array system that includes an array of receive antennas arranged in a focal region of a second lens such that an RF transmission from each transmit antenna maps to a corresponding receive antenna, wherein each transmit antenna not included within the first subset of transmit antennas is unused;
- and
- receiving the first plurality of RF signals at a first subset of receive antennas in the array of receive antennas to receive a first symbol.
A system for wireless communication, comprising:
- a first lens;
- a plurality of transmit antennas arranged in a focal region of the first lens;
- a plurality of on-off keying modulators corresponding to the plurality of transmit antennas, each on-off keying modulator and corresponding transmit antenna forming a transmit link;
- and
- a processor configured to map a first digital word into a selection of a first subset of the transmit links such that each transmit link in the first subset of the transmit links transmits an RF signal and such that each transmit link that is not in the first subset of the transmit links does not transmit an RF signal.
2 more elements
A system for wireless communication, comprising:
- a first lens;
- a plurality of receive antennas arranged in a focal region of the first lens;
- a plurality of low-noise amplifiers corresponding to the plurality of receive antennas;
- a plurality of envelope detectors corresponding to the plurality of receive antennas, each receive antenna and corresponding low-noise amplifier and corresponding envelope detector forming a corresponding receive link;
- and
- a processor configured to map a selection of a first subset of the receive links into a first digital word based upon which receive link receives a first RF signal.
